Changes since for U-Boot 0.1.0:
======================================================================
+* Patch by Jim Sandoz, 07 Nov 2002:
+ Increase number of network RX buffers (PKTBUFSRX in
+ "include/net.h") for EEPRO100 based boards (especially SP8240)
+ which showed "Receiver is not ready" errors when U-Boot was
+ processing the receive buffers slower than the network controller
+ was filling them.
+
* Patch by Andreas Oberritter, 09 Nov 2002:
Change behaviour of NetLoop(): return -1 for errors, filesize
otherwise; return code 0 is valid an means no file loaded - in this
